NASA has been building robotic lunar rover prototypes for decades. Why is the Moon not crawling with them? Because NASA insists on running a Survivor beauty pageant for everything and the lunar rovers were always the bridesmaid never the bride.
We haven't had a shortage of launchers for a decade, but all this capability remains stuck in development hell, and meanwhile China understands that you can just Do Things and there they are.
On Sunday, China is sending a hopper into Shackleton Crater at the Lunar South Pole to look for ice.
The West does not have this capability. The right time to be building hoppers was yesterday.
We're building it @insitu_space
